Regardles, imho, it has to be addressed. You can't keep telling stories about thousands of people dying and keep things too light, or it starts to fall apart thematically, I would think.

With Thanos in the picture, there remains the very real possibility that half the universe is about to get wiped out. And I'll bet you one shiny silver dollar that Feige and Company have no intention of showing a single casualty in that most massive of mass murders. It's like when the Death Star vaporized Alderaan --- nobody was clamoring to see all the dead bodies to "prove" that a terrible thing had just happened.
